1st, are you level 3, 6, 9, 12, etc?
If so, add 2 ability scores to up to 2 abilities, or take a feat.
If not, continue
- Change saves, actions per turn, and BAB

- Level up your HP
(hit die roll) + con mod
- Level up skills
(skills can have a maximum amount of points equal to 3+your level)

- Last, check if there are any special abilities your class gets
